We designed a retrospective cohort study of 111 patients who were surgically treated for congenital heart disease between 2017 and 2020. Equine pericardium was used in 58 patients and bovine pericardium was used in 53 patients. Recorded variables included demographic data, preoperative cardiac pathology, site of patch insertion, morbidity and mortality.
The overall survival rate was 94.5% and no deaths were related to patch insertion. None of our patients were reoperated on for patch related complications. Postoperative transcatheter intervention was needed in 2 patients (1.8%) one for dilatation of aortic arch stenosis after repair of hypoplastic left heart syndrome with equine pericardium and one for dilatation of pulmonary artery branches after repair of tetralogy of Fallot using bovine pericardium.
Equine pericardium is a safe patch material for reconstruction in congenital heart surgery. It may be preferable to bovine pericardium in cases requiring a complex shape or a pliable patch as in in arch reconstruction or for valve reconstruction.

Flexible assertive community treatment (FACT) is a multidisciplinary service model aimed at providing integrated care for people with severe mental illness. The model was developed in the Netherlands and is now used in several countries, such as Norway. The Norwegian service system is complex and fragmented, with challenges in collaboration. Limited research has been performed on FACT teams and other new integrative health service models as part of such systems. However, such knowledge is important for future adjustments of innovation processes and service systems. Our aim was to explore how FACT teams are integrated into the existing formal public service system, how they function and affect the system, and describe some influencing factors to this. We sought to address how service providers in the existing service system experience the functioning of FACT teams in the system.
Five focus group reassuring other services; this has reduced some gaps in the system. The way FACT teams function and needs of the existing system appear to have contributed positively to these findings. However, complexity and fragmentation of the system partly hamper functioning of the FACT teams.
The FACT teams in this study contributed to positive changes in the existing service system. They largely contributed to less complex and fragmented systems by forming a bridge and undertaking responsibility in the system and by collaborating with and reassuring other services; this has reduced some gaps in the system. The way FACT teams function and needs of the existing system appear to have contributed positively to these findings. However, complexity and fragmentation of the system partly hamper functioning of the FACT teams.This case study describes research, which is located in Turkey, where more than 750,000 Syrian refugees reside autonomously in Istanbul. The research developed and pilot tested a novel model for helping urban refugee families with limited to no access to evidence-based mental health services, by delivering a transdiagnostic family intervention for common mental disorders in health and non-health sector settings using a task-sharing approach. This case study addresses the following question What challenges were encountered in developing and piloting a low intensity trans-diagnostic family support intervention in a humanitarian emergency setting?
The rapidly growing scale of humanitarian crises requires new response capabilities geared towards addressing populations with prolonged high vulnerability to mental health consequences and limited to no access to mental health, health, and social resources. The research team faced multiple challenges in conducting this research in a humanitarian emergency setting challenge.The binding of transcription factors (TF) to genomic targets is critical in the regulation of gene expression. Short, double-stranded DNA sequence motifs are routinely implicated in TF recruitment, but many questions remain on how binding site specificity is governed.
Herein, we reveal a previously unappreciated role for DNA secondary structures as key features for TF recruitment. In a systematic, genome-wide study, we discover that endogenous G-quadruplex secondary structures (G4s) are prevalent TF binding sites in human chromatin. Certain TFs bind G4s with affinities comparable to double-stranded DNA targets. We demonstrate that, in a chromatin context, this binding interaction is competed out with a small molecule. Notably, endogenous G4s are prominent binding sites for a large number of TFs, particularly at promoters of highly expressed genes.
Our results reveal a novel non-canonical mechanism for TF binding whereby G4s operate as common binding hubs for many different TFs to promote increased transcription.

However, the role OPHN1 plays during neuronal development is not well understood. We investigated the role of the Drosophila OPHN1 ortholog Graf in the development of the mushroom body (MB), a key brain structure for learning and memory in insects. We show that loss of Graf causes abnormal crossing of the MB β lobe over the brain midline during metamorphosis. This defect in Graf mutants is rescued by MB-specific expression of Graf and OPHN1. Furthermore, MB α/β neuron-specific RNA interference experiments and mosaic analyses indicate that Graf acts via a cell-autonomous mechanism. Consistent with the negative regulation of epidermal growth factor receptor (EGFR)-mitogen-activated protein kinase (MAPK) signaling by Graf, activation of this pathway is required for the β-lobe midline-crossing phenotype of Graf mutants. Finally, Graf mutants have impaired olfactory long-term memory.
